Consuming large quantities of sugary carbonated beverages like Coca-Cola can impact several human organs, most notably the metabolic system involving the liver and pancreas. Excessive sugar intake places stress on the pancreas to produce insulin, while prolonged high fructose consumption can contribute to fat accumulation in the liver, leading to non-alcoholic fatty liver disease. Additionally, the high acidity levels and sugar content can affect dental enamel on teeth and place long-term filtration demands on the kidneys.
